Pipe inner wall grinding and polishing device

Abstract

The invention relates to a pipe inner wall grinding and polishing device. The pipe inner wall grinding and polishing device comprises a drawing rod (8), wherein a centering bracket (7) is arranged at the front end of the drawing rod (8); three second adjustable wheels (10) are arranged at the periphery of the centering bracket (7) uniformly; a bracket seat (5) is arranged on the centering bracket (7); the front end of the bracket seat (5) is hinged to a swinging bracket (2); a power part (3) is arranged at the front end of the swinging bracket (2); a grinding wheel (1) is arranged at the output end of the power part (3); a jacking part (4) is arranged in the middle of the swinging bracket (2); a first adjustable wheel (9) is arranged at the output end of the jacking part (4); a swinging bracket swinging angle limiter (6) is fixedly arranged at the rear end of the swinging bracket (2). The pipe inner wall grinding and polishing device provided by the invention improves the grinding or polishing efficiency and can effectively control the pressing force to the pipe inner wall so as to guarantee the final grinding or polishing quality.

Description

technical field [0001] The invention relates to a pipe inner wall grinding and polishing device, which belongs to the technical field of metallurgical equipment. Background technique [0002] With the continuous progress of industrial manufacturing technology, the quality requirements of the inner wall of pipe fittings are getting higher and higher, and it is required to grind or correct the size of defects such as retention, cracks, and sand holes in the inner wall of long circular pipes. In the past, manual hand-held grinders were usually used to grind or polish defects on the inner wall of pipes with large diameters and short lengths, and the work efficiency was low. For the grinding of inner wall defects of small diameter and long pipe fittings, a grinding wheel is usually installed at the end of a slender rod to grind or polish the inner wall of the pipe fittings, because the grinding wheel (or polishing wheel) compresses the inner wall of the pipe when grinding The fo...

In the past, manual hand-held grinders were usually used to grind or polish defects on the inner wall of pipes with large diameters and short lengths, and the work efficiency was low.

For the grinding of inner wall defects of small diameter and long pipe fittings, a grinding wheel is usually installed at the end of a slender rod to grind or polish the inner wall of the pipe fittings, because the grinding wheel (or polishing wheel) compresses the inner wall of the pipe when grinding The force is difficult to control, and the shaft driving the grinding wheel is long, which makes the grinding wheel (or polishing wheel) prone to vibration during grinding, which affects the quality of grinding or polishing
